Leveraging shared caches for parallel temporal blocking of stencil codes on multicore processors and clusters
Markus Wittmann, Georg Hager, Jan Treibig +1
Bandwidth-starved multicore chips have become ubiquitous. It is well known that the performance of stencil codes can be improved by temporal blocking, lessening the pressure on the…
Efficient multicore-aware parallelization strategies for iterative stencil computations
Jan Treibig, Gerhard Wellein, Georg Hager
Stencil computations consume a major part of runtime in many scientific simulation codes. As prototypes for this class of algorithms we consider the iterative Jacobi and Gauss-Seid…
LIKWID: A lightweight performance-oriented tool suite for x86 multicore environments
Jan Treibig, Georg Hager, Gerhard Wellein
Exploiting the performance of today's processors requires intimate knowledge of the microarchitecture as well as an awareness of the ever-growing complexity in thread and cache top…
